TRANSCRIPTUse Habit Stacking to Help Get HealthyA woman in Portland, Oregon started her daily exercise habit with one activity — walking her dog. Lindsay Kee then added movements to this daily activity. (Q1) Before leaving on the walk, she did some standing stretches. On her return, she did other exercises such as jumping jacks.jumping jacks 开合跳Over time, Kee added more exercises around the dog walk. She said adding exercises to an existing activity took the pressure off of creating a whole new daily exercise. And now more than a year later, she consistently exercises around the dog walk.Kee said, “I’ve found it to be really effective in helping me be consistent with things that I really want to do.”What Kee did is called habit stacking. Writer S.J. Scott created this term for his 2014 book of the same name. (Q2) The idea behind habit stacking is to attach something you want to start doing to something you already do every day.habit stacking 习惯叠加A common example is flossing your teeth after brushing them. However, you can use habit stacking in many areas of your daily life. Kee, for example, places her vitamins next to the coffee machine. This helps her remember to take them every morning.Exercise experts say habit stacking is especially helpful if you are trying to increase exercise time.Dana Santas is a movement expert who has trained more than 50 professional sports teams. She combines exercise habits with personal health care. (Q3) For example, Santas does push-ups before every shower. And she does leg exercises while brushing her teeth. She says that her electric toothbrush makes a sound every 30 seconds to remind her to brush different teeth. But she uses the reminder to change her exercises. “It’s perfect,” she added.push-up n. 俯卧撑Two minutes of exercise may not get you in shape. But experts say, every little bit helps. (Q4) Experts at the U.S. Centers for Disease Control and Prevention suggest getting 150 minutes of moderate activity, like a fast walk, every week. Or you could also get 75 minutes of very energetic activity, like jogging, every week. The health experts also suggest two days a week of strength training.moderate adj. 适度的，中等强度的Most people find keeping new habits difficult. And while habit stacking is not a perfect solution, it does help with one barrier — decision-making.Gretchen Rubin is the writer of Better Than Before: Mastering the Habits of Our Everyday Lives. She said habit stacking is one of the best ways to start and keep new habits. The technique helps to remove the barrier of deciding when or if to do something.Rubin shared a story of her college days. To help her stay active, she would only shower if she had exercised that day.She suggested combining the new, or what she calls “shaky” behavior with something you have to do or deeply want to do.(Q5) “So you have to do the shaky habit before you get to the strong habit,” Rubin said. (Q5) If she wants to listen to a podcast, her strong habit, she must do it while exercising on a running machine. For her, this will strengthen her shaky habit.Part III. KEYQ1. B. 细节题。题目出处为：Before leaving on the walk, she did some standing stretches. 意为：在开始遛狗前，她会做一些站立伸展运动。这表明Kee最初通过在遛狗前做站立伸展运动来培养锻炼的习惯。因此答案是B。Q2.

教学素材 | 人生旅途轻装上阵

The Art of Traveling Light through Life人生旅途轻装上阵词汇：考研 | 句法：六级 | 文本：考研刘立军 供稿Ancient philosopher Socrates embodied simplicity, owning little and even forgoing shoes. Despite this, he frequented marketplaces not to acquire goods but to appreciate the abundance he could live without, as he famously noted to an inquiring friend. 古代哲学家苏格拉底以其简朴的生活方式著称，他几乎一无所有，甚至常常赤脚行走。然而，正如他曾对一位好奇的朋友所说，他经常光顾市场，不是为了购买商品，而是为了欣赏那些他能够舍弃的丰盛物资。In the context of travel, ‘traveling light’ means moving unencumbered by excessive belongings, which translates into a more pleasant journey with less burden and greater freedom. This idea extends beyond the physical realm into a philosophy for living. This concept encourages us to question what constitutes a life traveled lightly ― is it minimal ownership like Socrates, or is there more to it? 在旅行的语境中，“轻装上阵”意味着不被繁重的行李所累，从而享受更加轻松愉快的旅程，减少负担，获得更多自由。这一理念不仅仅局限于物质层面，它更是一种生活哲学。这种思想引导我们前去思考：什么是轻装上阵的生活——它是像苏格拉底那样过极简的物质生活，还是有更多的内涵？The tale of King Midas reveals that an insatiable desire for possessions can lead to downfall. His wish to turn everything to gold, granted by Dionysus, turns tragic when the things he treasures most are lost to his greed, teaching him the peril of material obsession. 迈达斯国王的故事向我们揭示了一个深刻的道理：对财富的贪得无厌可能导致灭亡。他祈求将一切变为黄金，这一愿望虽由狄俄尼索斯实现了，但当那些他最为珍视的事物因他的贪婪而失去时，这一愿望最终酿成一场悲剧，让他深刻体会到了痴迷物质的危险。Humans naturally accumulate more than necessary, often driven by an innate instinct for survival, from securing homes for shelter to stocking food against hunger. However, for some, this need tilts towards excess, acquiring vast properties and collections of vehicles far beyond necessity, echoing Midas’s folly. While possessions offer convenience, they can also anchor one’s life with responsibilities and maintenance demands, whether it’s the upkeep of a lavish villa or the financial strain of an expensive mortgage, trading freedom for security. 人类出于生存本能，往往会积累超过实际所需的物品，从确保住所的安全，到储备食物以防饥饿，皆出此因。然而，对一些人来说，这种需求逐渐演变为过度的占有欲，他们积累了大量远超必要的财产和车辆，重蹈迈达斯的覆辙。尽管拥有这些财物能带来便利，它们也带来了诸多责任和维护的需求，无论是豪华别墅的日常维护，还是高昂房贷带来的财务压力，都是在以自由换取所谓安全感。Epicurus argued that the pursuit of pleasure should not result in greater distress. Our attachment to both possessions and burdensome thoughts impedes progress. Ancient philosophies, such as Stoicism, Cynicism, and Buddhism, guide us toward letting go of these material and mental weights to alleviate our lives. 伊壁鸠鲁认为，追求快乐不应该导致更多的痛苦。我们对财物的执着以及内心的负担阻碍了我们的进步。斯多葛主义、犬儒主义和佛教等古老哲学都在教导我们：应学会放下这些物质和精神上的重负，让生活变得更加轻松自在。Desires and aversions exert their own weight, where fulfillment leads to contentment and a sense of lightness, while unmet desires breed dissatisfaction and burden. Philosophical traditions across Stoicism, Buddhism, Christianity, and Islam prioritize non-attachment to worldly goods, viewing them as distractions from a path meant for those unburdened. 欲望和厌恶会分别带来不同的负担：当欲望得到满足时，人们会感到轻松和满足；而未满足的欲望则会引发不满和沉重感。无论是斯多葛主义、佛教、基督教还是伊斯兰教，这些哲学传统都强调对世俗财物的淡泊，认为它们是那些追求心灵自由之人路上的障碍，只会分散他们的注意力。The minimalist approach isn’t only about reducing physical possessions but also mental clutter. Letting go of future anxieties and past regrets brings psychological lightness, enhancing our overall well-being and allowing us to navigate life with ease. 极简主义不仅仅意味着减少物质上的财物，它还包含洁净心灵上的杂念。放下对未来的焦虑和对过去的遗憾，可以带来心理上的轻松，进而提升整体幸福感，使我们更加从容地应对生活中的挑战。After periods of global turmoil, embracing a nomadic lifestyle underscored the value of minimalism. The capability to work remotely with minimal equipment exemplifies the physical and metaphysical lightness sought by many. Whether it be in a hotel room or traversing international borders, the ability to live and work with just a suitcase is liberating. 在全球动荡之后，拥抱游牧式的生活方式更加彰显了极简主义的价值。只需极少的装备即可实现远程工作，这体现了许多人所寻求的物质和精神上的双重轻盈。无论是在酒店房间，还是穿梭于国界线之间，仅凭一只手提箱便能自在生活与工作，这一能力赋予人们极大的自由。The agility afforded by traveling light is akin to the experience of playing games like Skyrim with a nimble character. In life, being agile equates to adaptability ― being able to change course rapidly without the encumbrance of possessions or obligations. Ultimately, true lightness is achieved when one’s mind is unburdened by worries and desires, transcending even the most minimalist lifestyle. 轻装上阵所带来的灵活性，就如同在玩《上古卷轴5：天际》游戏时操纵一个敏捷角色的体验。在生活中，灵活意味着适应能力——能够在不被物质所累或义务束缚的情况下迅速改变方向。最终，当一个人的心灵不再受忧虑和欲望所困时，真正的轻盈感就实现了，这种状态甚至超越了最简约的生活方式所带来的自由感。An uncluttered mind allows for a truly light life journey, wherein the absence of mental strain makes even the smallest suitcase seem weightless. 一颗没有杂念的心能让生活旅程真正变得轻盈起来，那时，即便是一个最小的手提箱，在没有精神压力的情况下，也仿佛轻如鸿毛。【词汇】1. forgo v. 放弃2. unencumbered adj. 无负担的；没有阻碍的3. the tale of King Midas 迈达斯的故事。传说，希腊神话中的弗里吉亚王迈达斯贪恋财富，求神赐予点物成金的法术，酒神狄俄尼索斯满足其愿望。最后连他的爱女和食物也都因被他手指点到而变成金子。他无法生活，又向神祈祷，一切才恢复原状。4. insatiable adj. 不知足的；无法满足的5. folly n. 愚蠢；愚笨6. upkeep n. 保养；维修7. villa n. 度假别墅8. Epicurus 伊壁鸠鲁，古希腊哲学家。9. Stoicism n. 斯多葛主义，古希腊罗马时期的重要哲学流派，强调理性、自律、坚忍以及接受命运。10. clutter n. 杂乱的东西；杂乱11. nomadic adj. 游牧的；流浪的12. metaphysical adj. 形而上学的；抽象的；玄学的 13.

They are well understood and have a single cause.B. They are primarily linked to pre-existing health conditions.C. They are related to the severity of the initial COVID infection.D. They are varied and include many different abnormalities.Q3. What is the role of vaccination in relation to Long COVID, as discussed by Dr. Rylance?A. It increases the risk of developing Long COVID.B. It has no effect on the likelihood of experiencing Long COVID.C. It protects against severe COVID disease and Long COVID.D. It is ineffective once Long COVID symptoms have already begun.Q4. What can be inferred about the global impact of Long COVID and the need for healthcare recognition and support?A. Long COVID is a localized issue that requires specialized treatment centers.B. Long COVID is a widespread problem affecting diverse populations.C. Long COVID symptoms are universally recognized and treated the same way worldwide.D. Long COVID is not a significant concern for healthcare systems.Q5. What is the main idea of Dr. Rylance’s discussion on the challenges and support needed for managing Long COVID?A. The key is to raise awareness and ensure patients feel recognized and supported.B. The main focus should be on rehabilitation and improving quality of life.C. The primary challenge is developing a specific medical treatment for Long COVID.D. The most important aspect is to conduct more clinical trials for new treatments.Part II. TRANSCRIPTWHO’s Science in 5: What Is Long COVID?Vismita Gupta-Smith: If you have recovered from COVID but still have some symptoms, could that be Long COVID? How long do these symptoms last? Is there treatment available? Here to talk about Long COVID today is Dr. Jamie Rylance. Welcome, Jamie. Jamie, talk to us about Long COVID. How does it affect people?Dr. Jamie Rylance: Yeah. Thanks, Vismita, pleasure to be here. So Long COVID can happen to anybody after their acute illness. It can come on as a continuation of symptoms or new symptoms and it can last a long time. The problem is, the symptoms are very variable. Patients may have difficulty recognizing that they have it and healthcare workers, to be honest, can also struggle to identify it. (Q1) But if you’re a typical Long COVID patient, you might have fatigue, feeling tired all the time brain fog, difficulty concentrating, difficulty sleeping, shortness of breath. Those are the main symptoms, but there are so many others. One of the problems is that those symptoms can also represent other medical illnesses. So it’s really important to get the diagnosis right and healthcare workers and patients need to work together to do that. So when scientists have looked for what are the underlying causes of Long COVID, there’s many different abnormalities that have been seen. (Q2) Things like very small blood clots or altered immune cell responses, abnormal triggering or responses within the nervous system or changes in the usual bugs, the microbiome that we usually carry around with us. And that being so many different possibilities, there’s no single one diagnostic test. That said, we need to get patients onto treatment. We focus on the things that are bothering them, the symptoms, and making sure their function comes back to normal.diagnosis n. 诊断；（问题原因的）判断blood clot 血凝块；血块Vismita Gupta-Smith: Jamie, do people experience Long COVID differently? Are symptoms different and why? Dr. Jamie Rylance: Well, the obvious thing is no two people are the same and it can be very different. That said, we do know some things that might predict whether you’re more at risk of having Long COVID or for how long the symptoms might last for.Vismita Gupta-Smith: Jamie, talk to us about vaccination.Dr. Jamie Rylance: (Q3) So vaccination does help. It protects you against severe COVID disease and it protects you against Long COVID. At the other end of the spectrum, people who’ve had particularly severe disease are more likely to have Long COVID and the symptoms are likely to last longer. And that’s people who have been admitted to hospital or particularly to Intensive Care Unit. But we know that, the health of people before COVID is really important as well. So long-standing or pre-existing health problems. Respiratory disease, mental health problems but many others can increase the risk that you suffer long COVID. And therefore, it’s really important to try and keep and maintain a healthy lifestyle as much as possible. (Q4) So we know that Long COVID is a global problem. It can occur to anyone, anywhere in the world. What we need is for primary healthcare professionals to be able to recognize, assess and treat patients with Long COVID. And the way people access their healthcare will vary around the world. Sometimes there may be specialty services for COVID, sometimes there may be specialist doctors. But very frequently, and particularly where resources are limited, there are not. And so it’s really important that we empower primary healthcare providers to give patient centred care close to home. And that’s what we’re doing at WHO, making guidance to help healthcare workers deliver high-quality care and the education materials to support them to do so.respiratory adj. 呼吸的Vismita Gupta-Smith: So Jamie, how long do the symptoms last and even though we don’t have a pill, per se, how can we help people who are suffering from Long COVID? Dr. Jamie Rylance: Well, the first thing is that most people recover fully and that can take months and of course some people we know are badly affected for years. Although there isn’t a specific medical treatment, what we really need to do is access and treat patients for the problems that they have. Often that’s associated with rehabilitation, getting people back to functional status to enjoy life and health. There are specific medical treatments for some people and overall, that goes a long way to helping increase quality of life. So I’m optimistic in the science delivering more treatments and that’s hundreds of clinical trials going on at present. And I’d encourage people to get involved where they feel able and where they’re offered. So there’s hope, I think, in terms of new treatments. (Q5) But apart from the medical treatment, I think the biggest obstacle that people with Long COVID feel at the moment is that their disease is not recognized. They’re told that their brain fog or other symptoms are not real, and that’s demoralizing. So what they need is kindness and support through their treatment. And that comes from their family, their friends, their employers, because it’s in everyone’s best interest that people with Long COVID don’t feel alone and feel that they’re supported throughout their recovery. demoralizing adj. 使丧失信心的，令人泄气的Vismita Gupta-Smith: Thank you, Jamie. That was Science in 5 today. Until next time then, stay safe, stay health and stick with science.Part III. KEYQ1. B. 细节题。根据文本中的描述：“But if you’re a typical Long COVID patient, you might have fatigue, feeling tired all the time brain fog, difficulty concentrating, difficulty sleeping, shortness of breath.”可知，典型的长新冠患者可能会经历疲劳、脑雾、难以集中注意力、睡眠困难和呼吸急促等症状。因此答案为B。Q2. D. 细节题。文本中提到：“there’s no single one diagnostic test.” 以及 “Things like very small blood clots or altered immune cell responses, abnormal triggering or responses within the nervous system or changes in the usual bugs, the microbiome that we usually carry around with us.” 这表明长新冠没有单一的诊断测试，造成它的的潜在原因多种多样，包括许多不同的异常情况，如微小的血凝块、免疫细胞反应改变、神经系统的异常触发或反应以及体内微生物群的变化等。因此答案为D。Q3. C. 细节题。根据文本中的信息：“So vaccination does help. It protects you against severe COVID disease and it protects you against Long COVID." 可知，疫苗接种有助于预防重症COVID疾病和长新冠。因此答案为C。Q4. B. 推理题。文本中提到：“So we know that Long COVID is a global problem. It can occur to anyone, anywhere in the world. What we need is for primary healthcare professionals to be able to recognize, assess and treat patients with Long COVID”这表明长新冠是一个全球性问题，可以影响世界上任何人，需要基层医疗保健专业人员能够识别、评估和治疗长新冠患者。答案为B。Q5. A. 主旨题。在讨论长新冠的挑战和所需支持时，Dr. Rylance提到：“The biggest obstacle that people with Long COVID feel at the moment is that their disease is not recognized.”以及 “what they need is kindness and support through their treatment.” 这表明，长新冠患者面临的主要挑战是他们的疾病没有得到认可，他们需要的是在治疗过程中的善意和支持。因此答案为A。（本文图片来源于摄图网，版权归摄图网所有)

TRANSCRIPTImportant Terms and Ideas for Describing Artificial IntelligenceThere are several terms experts use to describe computer systems in the field of artificial intelligence. Recently, the French News Agency (AFP) defined some of the common terms and ideas used in that field. Here is a version for English learners:intelligence n. 智力，智能Artificial intelligence The first term is “artificial intelligence.” When asked what artificial intelligence is, the AI-powered ChatGPT system says that the term means “the simulation of human intelligence in machines that are programmed to think, learn and make decisions”. (Q1) AI’s main quality or characteristic is taking in large amounts of data and then processing it using methods from statistics. AI involves using ideas from many fields including computing, mathematics, languages, psychology, and others. Currently, the technology is being used heavily for investigating health issues, translating human languages, and predicting problems in machine tools and self-driving cars. But AI is affecting many fields of business and industry.simulation n. 模拟，仿真Algorithm A second important term is “algorithm.” (Q2) An algorithm is important to all computer operations. It is a series of steps or instructions followed by a computer program to get a result. Algorithms can give rules for an AI’s behavior, helping it to realize the objectives of computer program developers. Unlike a simple computer program, AI algorithms permit a computer system to “learn” for itself.algorithm n. 算法，运算法则Machine learning A third important term is “machine learning.” Machine learning is one method that researchers have used in their efforts to produce artificial intelligence. Machine learning lets computers learn from data without being directly programmed on what results to produce. In recent years, the field of neural networks has given important results. In a neural network, connections between some nodes are strengthened and others weakened as the system learns and makes changes. Learning can be “supervised.” This means the system learns to put new data into specific groups based on a model. For example, the system could learn to identify spam in an email or other messaging programs. “Unsupervised” learning permits the system to independently discover new areas or ways of doing things. These discoveries in the available data might not have been immediately clear. An example would be letting an online store identify buying trends in sales data. (Q3) “Reinforcement” learning adds a process of repeated trial-and-error. In this process, the system is rewarded based on its outcomes, causing it to learn and improve. One example might be a self-driving vehicle whose objective is to reach its destination as quickly as possible but also safely. That requirement would lead it to learn to stop at red lights although it requires additional time.neural adj. 神经的node n. 节点spam n. 垃圾邮件Deep learning (Q4) Deep learning owes its name to its use of many layers of neural networks. Raw data is examined by each layer in turn at growing levels of abstraction. Geoffrey Hinton received the 2024 Nobel Prize in Physics. Hinton is credited with developing deep learning. Hinton received the prize along with 1980s neural-network developer John Hopfield. Francis Bach, head of France’s SIERRA statistical learning laboratory, said this about deep learning: “The more layers you have, the more complex behavior can become, and the more complex the behavior can be, the easier it is to learn a desired behavior efficiently.” The method might help lead to scientific discoveries.Language models We now turn to large language models (LLMs). These might be the most popular example of generative AI. Large language models’ power tools like OpenAI’s ChatGPT or Google’s Gemini. Such systems are able to write long papers, answer legal questions or even produce a cake recipe based on their statistical models. But the technology is still new. (Q5) LLMs can suffer from “hallucinations” — the creation of content that is false or incorrect.hallucination n. 幻觉，虚构内容Artificial general intelligence A final important term is artificial general intelligence (AGI) — one the big goals of the whole AI field. (Q6) AGI suggests the unrealized dream of a machine able to reproduce all human processes of human thinking. People who push the idea include OpenAI chief Sam Altman and his competitors at Anthropic. They consider such a system to be within reach. The goal is to use large amounts of data and processing power to train LLMs that are increasingly powerful. But critics say that LLM technology has important limits, including its ability to reason. Maxime Amblard, computing professor at France’s University of Lorraine, told AFP last year, “LLMs do not work like human beings.” Amblard added that humans, as flesh-and-blood intelligent beings, are “sense-making machines” with different abilities from today’s computer systems.Part III.

TRANSCRIPTReport: Language, Traditions Central to National IdentityLuciana de Oliveira considers herself transnational. That means she is more than one nationality. de Oliveira grew up in Brazil, but she moved to the United States for her studies. She became a U.S. citizen in 2017.transnational adj. 跨国的；多国的de Oliveira has some strong feelings about national identity. She believes speaking a country’s majority language is a very important part of one’s national identity. de Oliveira speaks both Portuguese and English.A new study found that most people around the world share those feelings about language and national identity.The Pew Research Center carried out the study and released the results last month. Pew’s study centered on people’s ideas about national identity. It included answers from people in more than 20 countries.(Q1) Pew researchers asked study participants about four aspects, or parts, of national identity: language, traditions, birthplace and religion. They found that language is by far the most valued aspect of national identity.In fact, a median of 91 percent of people across 21 countries said that speaking a country’s most common language is “important for being considered a true national.”Traditions and customs are also key to national identity, the study found. Beliefs about the other two aspects – birthplace and religion – were more divided.VOA Learning English spoke with several people who live in countries that were included in the study. Among them is Jorge Catalan. He has lived in Mexico most of his life. The Pew study found that 93 percent of respondents from Mexico said that speaking the country’s main language – Spanish – is important to national identity.Catalan said he agrees that speaking Spanish is very important. But he added that it is regrettable.He said, “Mexico is a place where we have around 68 spoken languages besides Spanish.” He noted that the government has pushed Spanish as the main language throughout history and has turned it into a “must-have tool.”Agatha Janzen was born and raised in Canada. Pew researchers found that more than 80 percent of Canadians say that speaking the country’s language is important to national identity. In Canada, both French and English are official languages.Janzen said that “speaking one of the official languages is important to being Canadian for practical reasons.”(Q1) Traditions and customs are also a central aspect of national identity, the study found. Results showed 81 percent of people believe sharing their country’s customs and traditions is somewhat or very important to national identity.The Pew study found that 67 percent of Brazilians consider practicing customs and traditions an important part of national identity. That is the fourth lowest percentage of all the countries included in the study.But customs and traditions are important to de Oliveira. To feel closer to her Brazilian identity, she said she wears jewelry and shoes from Brazil and follows and supports Brazilian soccer.Mexico is tied with the highest percentage of respondents who answered that customs and traditions are an important aspect of national identity. But for Catalan, they are not so important. He noted that Mexican traditions have changed over time. He added that he does not take part in many Mexican traditions, “but I still feel proudly Mexican.”Beliefs about the two other aspects of national identity – birthplace and religion – were more mixed. A median of 58 percent of respondents from 23 countries said that being born in a country is important to national identity. An even lower number of respondents – 42 percent – said that being a member of the country’s main religion is important to national identity.(Q2) Respondents from Mexico and Indonesia had the strongest feelings about the importance of birthplace as central to national identity, at 91 percent.Calatan, who was born and lived most of his life in Mexico, agrees somewhat. “If you are born outside of Mexico and never lived in it, it would be difficult to get a real sense of what being Mexican means.”(Q3) But Janzen, the Canadian, said, “Being born in Canada has nothing to do with being Canadian.” For her, Canada is a melting pot and offers refuge to those who need it.refuge n. 庇护；避难These ideas match the results of the study. Countries where immigrants make up a smaller share of the population tend to see birthplace as a more important aspect of national identity. (Q4) Countries with a greater share of immigrants are more willing to accept those born outside of the country as true nationals.Less than half of people in most of the countries in the study do not feel religion is important to national identity. All of those who spoke with Learning English said they agreed that religion is not an important part of national identity.Christine Huang is a research associate at the Pew Research Center. She is one of the writers of the study. She told Learning English, “This question of belonging in a country is related to other work we have done to measure how connected people feel to each other.”Huang added, “When looking at how people relate to others in their community, in their country, and all over the world, people most frequently report feeling close to others in their country.”|Part III. KEYQ1. A. 主旨题。文本中提到：“Pew researchers asked study participants about four aspects, or parts, of national identity: language, traditions, birthplace and religion. They found that language is by far the most valued aspect of national identity.” 以及“Traditions and customs are also a central aspect of national identity, the study found.”这表明研究参与者普遍认为语言和传统是民族身份最重要的部分，所以民族身份主要由一个人的语言和传统塑造。因此答案为A。Q2. C. 细节题。文本中提到：“Respondents from Mexico and Indonesia had the strongest feelings about the importance of birthplace as central to national identity, at 91 percent.” 这表明墨西哥和印度尼西亚的受访者中有91%的人认为出生地对于民族身份认同至关重要。因此答案为C。Q3. B. 推理题。Janzen表示：“Being born in Canada has nothing to do with being Canadian. For her, Canada is a melting pot and offers refuge to those who need it.” 这表明 Janzen 认为出生在加拿大与成为加拿大人无关，加拿大是一个大熔炉，为需要的人提供庇护，这意味着加拿大的民族身份认同是包容性的，不严格依赖于任何单一标准，如出生地或语言。因此答案为B。Q4. D. 推理题。文本中提到：“Countries with a greater share of immigrants are more willing to accept those born outside of the country as true nationals.” 这意味着拥有更多移民的国家更愿意接受在外国出生的人作为真正的国民，可推测出他们认为出生地对于国家身份认同不那么重要。因此答案为D。Q5. C. 主旨题。文本通过展示不同国家和个体对于语言、出生地和宗教在民族身份中重要性的不同看法，表明民族身份的概念在不同人群和国家之间存在差异。特别是对于出生地和宗教的看法更为混合，这表明民族身份的构成因素在不同文化和个体中有着不同的解读。因此答案为C。（本文图片来源于摄图网，版权归摄图网所有)
